.nonnen GBINDING on roLIsHING MACHINE Application led December 17, 1924.' Serial No. 756,542.

To all whom 'it may concern:

Be i known that I, MICHAEL BARoIcrrow- SKI, a citizen of Poland, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Roller Grinding or Polishing Machines, of which the following is a specification.

The present invention relates to roller grinding machines, and its main object is to provide a machine of the type which is simple in construction, which may be easily transported andl which may be easily manipulated. A further object of the invention is to provide the machine which is capable of vertical, `transversal and longitudinal adjustment in respect to the rollers to be ground.

With the above general objects in view and others that will appear'as the nature vof the invention is better understood, the same consists in the novel construction, com' bination and arrangement of parts hereinafter -more fully described, illustrated in the accompanying drawings and pointed out in' the appended claims.`

-In the drawings forming a part of this application, and in'which .like designatingcharacters refer to corresponding parts' throughout the several views,

Figure 1 is a rear elevational view ofthe machine; j

Figure V2 is a side sectional view of the machine taken on line 2-2 of Figure l1;

Figure 3 is a top plan view of the machine and Figure 4 is a sectional view through ai portion of the machine on line 4--4 of Figure 3. Y y

Referring to the drawings in detail, 1n

Vwhich like reference characters designate corresponding parts throughout the several views, 10 designates a platform or bed supported in any suitable manner above the- A floor and adapted for vertical adjustment so that it may be set horizontally on a level or inclined forwardly or rearwardly.' .As

'plat orm. While I turnedv in the` manner of turn-buckle connections to raise or lower the vplatform in traversing the lengths of the screw sections or lShanks 12. The sockets 13 are provided'with lower shank yportions or stems 15 formed with sockets or cups 16, preferably substantially elliptical or egg-shapled and open at the bottom to receive similarly shaped tread members' 17 having their enlarged portions held in the cups 16 and their lower portions rejecting ,therefrom for contact with the oor surface. By this means, and owing to the fact that the cups are free to turn on the smooth surfaces of the tread members while the latter are held stationary due to the frictional engagement thereof with the floor caused by the weight of the platform and other parts of the machine, by inserting a suitable bar or implement in the sockets or apertures 14 and turning the lower sections 18, the latter and the cups 16, will be free to turn on the tread inembers 17 -so as to take' up or extend the sec- Y tions 12 due tothe threaded engagement, thus shortening or lengthening the legs and elevating or lowering the platform.

` The platform or table 10 is adapted to adjustably support the superstructure and working parts of the roller grinding machine, together with the grinding wheels, and for this purpose is rovided at the sides Ywith flanges 18 and at t e back with a ledge or flange 18 disposed along its edges, while the'front edge isreely open and unobstruct- 'ed therebetween. Adjacent the sides of the ledge 18 andin spaced arallelf relation thereto, rails '19 are secure upon the platform 10 and have undercut faces 2O providing guideways in connection with the sides of the ledge for slidably receiving transverse tracks 21 at the ends and lower corners of a frame structure or bed 22, which is thereby mounted for transverse adjustment forwardly and rearwardly upon the platform. As shown, tlie tracks 21 are beveled to fit the undercut faces 20, thus retaining the frame structure against vertical displacement when moved back and forth, and especially when in a projected or overhanging osition with res ect to the fron-t of the ave shown the frame structure or bed 22 as composedof vertical, longitudinal and cross members forming an open frame, it is to be understood that this vis principally for lightness in weight,` ac

oessibility and so that it maybe readily cleaned, lubricated and maintained in work- It may be formed as an ining condition.

or of parts suitably secured tegral structure together and in either case, the tracks are 4held in the guideways in the manner of dove-tail connections and retained from vertical displacement as well as rearward displacement by the ledge 18 at the back of the platform.

In order to adjust the bed transversely back and forth, suitable means are provided between it and the platform, such means being shown in the form of screws 23 firmly secured to the rear longitudinal member 24 of the bed 22 in such a manner as to permit adjustment, as by nuts 25 or other suitable means engaging the screw upon opposite sides of the member or bar 24. These adjusting screws extend rearwardly in horizontal ositions and have threaded engagement with threaded apertures in upstanding portions of angle brackets 26 secured to the platform 10 at its rear edge and adjacent each end of the platform and bed. The screws 23 may be manually or otherwise actuated independently as desired to shift the bed back and forth transversely of the platform, thus permitting minute and accurate adjustment as well as retention thereof in any desired working position.

The top lof the frame er bed 22 serves to support a longitudinally adjustable and movable carriage 27 which carries the grinding rollers or wheels constituting the traveling tool of the machine. For this purpose,

the front of the bed at the top is provided with a longitudinal bar or guide member 28 having an undercut groove 29 forming Ia guideway receiving for sliding movement therein, the beveled forward edge of the carriage 27. The back of the carriage rests in a recess 31 forming a shoulder 32 to lprevent rearward displacement of the carriage and guide it in its movements across the machine and throughout the length of the rollers to be ground. In order to im-' part the necessary movement to the carriage to adjust the same longitudinally or cause reciprocation thereof, a rack bar 33 is formed 1n the back of the carriage above the shoulder 32 and adapted to slide thereon, it

` being understood that the parts so engaged should be properly lubricated. This bar has rack teeth 34 on theunder side at the back or rear side of the carriage and bed, and has reduced ends v35 sliding under keepers 36 at the rear ends of strips \37 secured upon the ends of the bed as clearlyv seen in Figures 1 and 3 of the drawin s. The keepers are formed by reducing t e thickness or cutting outl the strips or plates 37 at the bottom and at their rear ends to form grooves slidably receiving the reduced ends of the rack bar and constituting stops to llniit the movements of the carriage in either direction by engagement with shoulders 38 formed by said reduced ends. A pinion 39 is rotatably journaled on a shaft 40 at the back of the bed through the top longitudinal frame member thereof, in which suitable bearings and retaining means may be provided. This pinion meshes with a largerl pinion or gear 41 journaled in a bearing 42 formed with or bolted to the back of the frame structure or'bed 22 as shown in'Figure 1, upon a shaft 43 carried by the bearing. The gear 41 is suitably turned as by hand,a handle 44 being shown for this purpose so that rotation may be imparted to the meshing pinion 39 at increased speed and by engagement of this pinion with the rack teeth 34, to reciprocate or 'slide the carriage crosswise of the machine, and longitudinally of the platform, frame structure or bed, and the rollers to be ground and polished.

The carriage 27 supports the grinding wheels or polishing rollers for acting upon the rollers or rolls of a rolling machine or mill to be ground as to smoothness, uniformity or other surface to be produced, and for this purpose a substantially U- shaped bracket 45 is provided thereon, including a vertical rear part and horizontal upper and lower arms 46 and 47 which may be reinforced by an intermediate strut 48. The free forward ends of the arms form bearings, being` bifurcated to take shafts 49 which are journaled therein and have grinding wheels 50 fixed thereto. These wheels may be used for grinding or polishing and are formed of suitable abrasive material, such as carborundum, emery or the like, or of polishing material, and are adapted to be driven in opposite directions in engagement with the rollers or rolls 5l to be ground.

In order -toV drive these grinding wheels, af motor such asan electric motor 52 may be mounted upon the carriage 27 and 'has a pinion 53 on its rotor 'shaft in mesh. with a large gear 54 fixed to a shaft 55 journaled in the bracket-45 at the strut or vertical part 48. rThe gear 54 in turn meshes with a gear or pinionl 56 liXed to the shaft of the lower grinding wheel 50 to impart rotation thereto in one direction, preferably counterclockwise. The other end of the shaft 55 has a pinion 57 fixed thereto and meshes with a larger pinion or gear 58 journaled on It should same or dierent as desired by simply varying the gear ratio. It will also be understood that the grinding Wheels may be driven in the reverse directions from those described while in contact with the rolls to be ground, and that the diameters thereof may be the same or different, according to the nature and use of the rolls, as employed in rolling sheet metal or in other mill work Where suchrolls or rollers are employed. Furthermore, a suitable reservoir 61 may bc mounted upon a bracketi 62 supported upon the bearing bracket 45 and provided with outlet pipes 63 leading over the wheels 50 for the purpose of flushing, lubricating and cleaning the same of the abrasive material or shavings, generally in powder form, resulting from Vthe abrasive action in the grinding1 and polishing of the rollers or mill ro s.

' l It will thus be seen and manifest that I have provided a novel and desirable roll machine which may be easily magrin 0 nipuilgebd, adjusted `and transported, and by the rolls ,f nally and transversel which the grinding wheels can be accurately adjusted or inclined to properly conform to to be ground irrespective of their diameters and relative positions vertically, and that With the combination of three major adjustments, namely, vertically, longitudi- X of the parts of the inachlne, the grinding wheels may be positloned for any required service to act upon rollers or rolls of any diameter, length, relatlve sizes or outline, that is whether cylindrical orformed with other regular or irregular surfaces. It is also to be understood that this work ma be quickly and efficiently carried on by tiis machine, which latter has its parts so related as to prove strong and serviceable in use with few parts unlikelyl to get out of Working order and capable of economical production, thereby facilitating quantity manufacture. Moreover, I do not desire to be limited to the exact details' shown and described as such changes in the form,relation and structure of the parts may be made as do not depart from the spirit and scope of the invention as will bey hereinafter defined and claimed.
